INSTALLATION
COMPONENTS
The heat pump water heater system is modular and comprises three main
components: the heat pump water heater, storage tanks and primary circulator.
An auxiliary booster and/or circulator may also be employed as part of the
system. The water heater must not be operated until all components are
assembled.
Do not tilt the heat pump more than 45° from the vertical. This will unsettle
the refrigerant gas and compressor lubricating oil. If the heat pump has been
tilted more than 45° from the vertical during handling, it will need one hour to
settle before the power to the water heater can be switched on, otherwise
damage to the compressor may result.
If the heat pump is tilted whilst conveying it on stairs, the compressor must be
braced adequately to prevent undue strain being applied to the piping and feet.
WATER HEATER LOCATION
953 series models above 50 kW are designed to be installed outdoors only, with
adequate supply of fresh air. Good performance is obtained when the heat pump
is supplied with unrestricted supply of fresh air. Failure to observe the above
recommendations may lead to lower than expected performance or problematic
operation of the heat pump.
The water heater should be installed close to the storage tanks and its position
chosen with noise, safety and service in mind. Make sure the air inlet and fan
outlet grilles are clear of obstructions and shrubbery and they are unlikely to be
touched by people (especially children).
It is advisable to install the water heater away from bedroom or living room
windows as the system can generate a noise of up to 69dBA (at 3 metres from
the water heater) whilst operating.
It is recommended the water heater be installed at ground or floor level.
The water heater must stand vertically upright.
Note: to assist with condensate drainage, the heat pump has a 2.5 degrees slope
towards the drains. Do not level the product.
Clearance must be allowed for servicing of the water heater. Refer to page 42
for clearance data. The water heater must be accessible without the use of a
ladder or scaffold.
You must be able to read the information on the rating plate. Remember you may
have to remove the entire water heater later for servicing.
